I am using a google document survey to have users enter times in a
military
format. The result is pasted into excel as a "General" format number,
like
2253 to represent 10:53PM. They do not enter the semicolon between hours
and minutes.

I need to see the number of minutes between two times, such as 2257 -
2253
or 4 minutes.

How can I convert general numbers, some of which are 04 to represent
00:04
AM, to serial times or time format?

Thanks very much in advance.

And a numeric solution:

=(INT(A1/100)+MOD(A1,100)/60-
(INT(B1/100)+MOD(B1,100)/60))*60

And another method, if you have either Excel 2007+ or have installed the
Analysis Tool Pak:

=(DOLLARDE(A1/100,60)-DOLLARDE(B1/100,60))*60

Another method (making use of the formula David posted)...

=1440*(TEXT(A1,"00\:00")-TEXT(B1,"00\:00"))
